Re: Feb status update for Fedora Infrastructure Apprentices

[Corey Sheldon]

0. Corey84 (same on IRC)

1. Not had a chance of late to dive in among other projects but planning to.

2. It has not yet but talking / dealing with several members in -admin,
-server, -and devel/-qa  has.

3. been looking at them   casually but not had chance to dive in (sadly
over-committed in some projects til Mid March)

4. Most certainly

5. Quite like the ones in place but a presence at a maker/hackerspace might
help with membership / interest pooling.

6. Time Management

7. Most this week mostly the ambassador and devel ones

8. Any form of art in the most general sense, as relates to linux and
Fedora the Server and Workstation installs

Yeah, there's two crons that are failing due to lack of fedmsg. :(

That is an excellent idea. ;) 
The docs all look good/accurate to me. ;)

If it would help that we have tracebacks from the mm2 mirrorlist for
when a bad pkl is loaded (the mm1 ones just fail, but the mm2 one does
provide a traceback):

Sounds good. 

There's some minor changes to make in mirrorlist rpms, but once thats
done we can look at replacing the other mirrorlists anytime. 

For the other parts, I think we will need to just create them all in
production and run them in parallel to the mm1 setup for a short time
until we are ready to cut over.

Hmmm, not exactly what I expected:


  504 Gateway Time-out

The server didn't respond in time.

When we were talking about the project at PyCon NZ, Robert said he
planned to use it for something in relation to OpenStack's
infrastructure, but I don't recall the details. If you wanted to know
more, it may be worth getting in touch with him directly.

Nick.
